(Delco Times) Former Pennsylvania U.S. Sen. Arlen Specter is facing another health crisis as he battles another form of cancer, according to a report on CNN.

This morning Specter’s office confirmed he is having another health issue and “plans to win this battle as well.”

Specter represented Pennsylvania in the U.S. Senate from 1980 until 2011. For most of those years he was a moderate Republican. But he switched parties in 2009, becoming a Democrat when he said the GOP had become too strident in its right-wing beliefs.

He was challenged – and defeated – in the Democratic primary, by then Delco Congressman Joe Sestak, D-7, of Newtown Square.

Specter has had numerous health battles in his long career, including a brain tumor and and non-Hodgkins lymphoma.
